100445-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 100445-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,4,4 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 100445-34:
(8*1)+(7*0)+(6*0)+(5*4)+(4*4)+(3*5)+(2*3)+(1*4)=69
69 % 10 = 9
So 100445-34-9 is a valid CAS Registry Number.

An improved method for the synthesis of active esters of N-protected amino acids and subsequent synthesis of dipeptides
Takeda,Ayabe,Suzuki,Konda,Harigaya
, p. 689 - 691 (2007/10/02)
4-Dimethylaminopyridine-catalyzed reaction of mixed carbonates 3 with N-protected amino acids 4 gave the corresponding active esters 5-9, from which dipeptides 11-18 were synthesized by aminolysis with amino acids 10.
